+monkeysphere (0.23-1) unstable; urgency=low
+
+ * There has been a major interface and data refactoring. Please see the
+ man pages for details. Major changes are listed here:
+ * For end users: monkeysphere-ssh-proxycommand is no more.
+ its functionality has been folded into monkeysphere as a subcommand.
+ So if you are currently using:
+ ssh -oProxyCommand='monkeysphere-ssh-proxycommand %h %p'
+ plese use instead:
+ ssh -oProxyCommand='monkeysphere ssh-proxycommand %h %p'
+ * For sysadmins: monkeysphere-server has been split into
+ monkeysphere-host (for publishing the ssh host key of your machine)
+ and monkeysphere-authentication (for setting up your machine to
+ authenticate users via the OpenPGP Web of Trust)
+ * For too-curious sysadmins: the layout of /var/lib/monkeysphere has
+ changed dramatically. If you did any tricky tweaking of the files in
+ there, you probably want to check that your changes have been
+ preserved after the upgrade. The old files can be found in
+ /var/lib/monkeysphere/backup-from-0.23-transition.
